To all whom it mag/concern: 7

Be it known that I, /VILLIAM. Cox, a citizen 'of'the United States, residing Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain net and useful Improvements in .iittachment Devices for Vehicle Bumpers andliumper Brackets, of which thefollowing is a specification.

and bumper brackets, andthe improvement resides in the simple clip and bolt device herein shown and described and more concisely pointed out in the claims.

In the annexed drawing, Fig. l is plan viewof a portion of a chassis frame and av spring bar bumper 'affixed thereto. by means of a pair of my devices, and Fig. 2 is aside view of thesameparts. Fig. 3 larged cross section of the channeled frame and thefastening device on line 3-3 of Fig. 2. Fig. 4: is a perspective view of the clip itself. 5 is a plan view, and Fig. 6 a side View and section of a modified form of bumper supporting arm affixed to the frame by a boltv and one of my devices.

Various devices are used to secure a bumper or a bumper supporting member upon a vehicle frame, but as nearly all auto mobile frames possess channeled side members A a common practice is to use hook bolts, Ubolts, and supplemental devices, in making such attachments. The present invention involves instead, the use of a straight carriage bolt B and an angle iron clip (I used together in such a way that a rigid non-turning clamping connection may be effected quickly and conveniently to any channel iron frame, and in which the clip itself will support and align the bolt when connected loosely or tightly, to the frame. The clip is also particularly designed to facilitate the use of a bolt where the room or space to make the connection is crowded or limited especially at the inner open side of the channel where it is customary to cover the channel with a splash pan or apron. Thus, bolt B is of a common type possessing a round screw-threaded shank 2, a square neck 8, and a rounded heat Clip C consists of a short angle-iron section having a relatively long forked flange 5 bent upwardly at its free extremity at an angle of about forty-five degrees, the notch 6 ex My invention relates to an improvement in attachment devices for vehicle bumpers hangi is an entending downwardly to the bend, and the} bent extremities providing two upwardlyextending, bearing fingers 7- 7 atequi-distaut points from the medial line of the slot; A. squarejopening 8 is formed in the vertical 9 of the clip directly opposite and in linewith notch ca receive the square neck 3 of the bolt when the round shank of the I bolt extends throughand rests in the slot between the two bcaringorfcontact fingers 7+7... "l -he upper free extremity of the vertical flange 9 of the clip is turned inwardly and downwardly to provide an over-l lip or lateral projection lOhaving a I it end edge 1.1 lying in a slightlt. higher horizontal plane than the. end edgts of the twoiingers 7+7 and parallel with said end edges. I N is shown, lip 10 is roundedfand curled v downwardlyand is also. relatively short to 'mitthisportion of the to be easily, V 'l upwardly in a very small space be-. twe n the end edge of thebottom flange '12 of the channelA and the depending apron a, see l ig. 3,.intoseating and seizing position upon lange 12. If tension isfnovv ap ,1 pliclktoboltfB thelip lObecoinesthejful lf cri'un'of a movementwhich causes thetwo be ring fingers to contact with the bottom side of flange 12, thereby clamping the clip rigidly to the fiange, and the bolt may rest eventually upon the horizontal flange of the clip between the two fingers. The straight edge 11 and the two fingers 77 clamp the clip squarely against the flat surfaces of the flange and the clip may be relatively narrow and still elfect such square seating engagement. In this way the strain and weight carried by the clip and imposed on flange 12 are distributedv over a wide area and an effective lock and fastening obtained which is capable of sustaining heavy Weights and severe shocks and blowswithoutv injury to the frame.

lnusing this device for attaching a bumper arm o or other bracket member to the channel member A, the screw-threaded end of the bolt may pass through an opening in the arm or bar 6 as shown in Fig. 3, and a lock-washer l-i and nut 15 used to draw up th bolt and clamp the arm or bar flatwise against the vertical outer face of channel member A. A similar bolt and clip attach ment may be made for a hanger H for the arm or bracket of a bumper, as shown in 110 Figs. 1 and 2, where the upper flange of the channel member A is also engaged by a clip by means or" a bolt 18 which passes through said member, and also a bolt B and clip C as herein described.
